What Causes Diarrhea?

From the food you eat to life’s stresses to catching the stomach flu, there are many causes of diarrhea. Most diarrhea triggers are from everyday events, foods that might upset the stomach, poor gut health, diet or common viruses. However, some cases may signal an underlying medical condition.

Diarrhea can be caused by various factors. Temporary diarrhea usually lasts one to two days and can be a result of food ingested, a viral or bacterial infection, or even traveling. If you have diarrhea lasting more than two days, or recurring diarrhea, we recommend seeking advice from a professional.
